RESEARCH INTERESTS:

Dr. Goodell joined the faculty in 1975, with interests in geochemistry, economic geology, mineralogy, and Mexico. He has a long and continuing interest in semi-metal and sulfosalt geochemistry and how they relate to economic geology. Semi-metal boiling in epithermal systems is an idea currently being tested. Sulfosalts also serve as an entry into materials research.

Uranium resources in volcanic and volcaniclastic rocks has also been an extended research activity for Dr. Goodell, including the organization of national (1979) and international (1984) meetings on the topic at UT El Paso. His expertise has taken him to China (1987), Argentina (1995), and as an invited speaker on the topic at the International Geological Congress in Beijing (1996). This avenue of research has expanded into the environmental issues of nuclear waste disposal. Field sites are under study which serve as analogues for high- and low-level nuclear waste performance assessment studies.

Helicopter-to-burro mapping in the gold belt of southwestern Chihuahua gives ground truth data in support of the new 'pull-apart' basin we just discovered. Additional projects include exploration for optimal locations for salinity gradient solar ponds, bioremediation of heavy

Groundwater quality and movement in downtown El Paso-Cuidad Juarez are being studies. The perched aquifer has been mapped for the first time using RCRA Violator and LST Fields, and the aquifer was found to be breached in several sites.

Dr. Goodell continues to teach in the M.S. program in environmental engineering at the Universidad Autonoma de Cuidad Juarez (UACJ), where he teaches hydrogeology and other environmental topics, and advises graduate students. He was also part of a research group in Juarez which produced the 1.2 gigabyte "Ordanamiento Ecologico Territorial de Los Medanos de Samalayuca," perhaps the first step in making the dune area a national park.

Dr. Goodell has been involved in curriculum reform on the undergraduate level for several years. The mineralogy/petrology sequence has undergone significant modernization and change, including HTML transitions. In addition, he initiated the annual "Celebration of Our Mountains" event, which consists of hikes and other activities for the public. He is now central to a group effort to put the Franklin Mountains on the WEB. Watch for the initiation of the Franklin Mountains Multimedia Information and Learning Site (FMMMILS), where you can zoom in and out 15 orders of magnitude of scale!

Between 1990 and 1994 Dr. Goodell was manager of the RCMS-UTEP program, a NSF-funded activity designed to enhance minority participation in the sciences and engineering. He organized discussion sessions/luncheons for mentors, and expanded the program.

The long-time belief of Dr. Goodell that the university is the place where one "learns how to learn" is being borne out by modern educational philosophy. It is a continual challenge to provide that challenge.
